To all whom it may concern.-

Be it known that I, JOHN DUGDILL, a subject of the Queen of 4Great Britain, residing at New Moston, Failsworth, Manchester, in

the county of Lancaster, England, have invented certain new and useful Improvements in Machines for Combing Cotton, Silk, or other Fibers, (for which I have obtained Letters Pat ent in Great Britain, numbered 8,378, bearing date July l1, 1885,) of which the following is a specification.

My invention relates to improvements in those machines for combing cotton, silk, and other fibers in which a revolving nipper and combing cylinders are employed; and my improvements consist chiefly in certain novel arrangements and combinations of the parts of such machines as hereinafter described, and as pointed out in the claims.

In order that my invention may be fully understood and readily carried into effect, I will describe the accompanying drawings, reference being `had to the letters marked thereon. Y

Figure lis a side view of the machine, showing the position of the reciprocating nippers when opposite the revolving nippers. Fig. 2 is a longitudinal section of the machine, showing the reciprocating nippers in position to present the tuft to the revolving nippers and showing other pairs of revolving nippers in position to present one tuft to the second combing-cylinder and another tuft to the delivery-rollers. Fig. 3 is a plan of the machine. Fig. 4. shows some of the parts in section which are shown in Fig. 2 and shows the reciprocat ing nippers in position to present the tuft to the first combing-cylinder. Fig. 5 is a longitudinal section of part of the machine with 4o the reciprocating nippers open and showing the revolving nippers 011 the other side open, having just delivered the tuft to the deliveryrollers. Fig.6 is a similar section to Fig. 5,

but showing the parts in a different position. Fig. 7 is a plan of part of Fig. 6.

The greater part ofthe framing of the machine is omitted in these views for the sake of clearness.

On the shaft a, which is driven from the first motion shaft in any convenient manner, is

mounted the second comb-cylinder b. The shaft'oJ drives the shaft c by the train of wheels a a2 a3, (shown in Fig.'3,) so that the shaft o and the first comb-cylinder b mounted npon it revolve respectively at the same speed as the shaft a and the second combcylinder b. Also fixed on the shaft c is a stud-wheel c', (shown in Fig. 1,) which engages with and drives a star-wheel d, on the boss of which is formed or fixed a pinion dx, which thuis `re lceives intermittently a revolving motion, which motion is transmitted by the train of wheels cl d2 d3 d4 d5 to the lap-rollers ee upon which the lapfis laid.

The lapfis uncoiled by friction when the rollers e e receive their intermittent motion, as described, and is conducted by a guide-plate (not shown) to the front feed-rollers g g, of which the lower roller g is driven by a pinion h on the boss of a star-wheel h, gearing into a pinion g2 on the roller g, as shown in Fig. 3.

The star-wheel h is actuated by the studwheel t', which is fitted loosely on the shaft j and is driven from the shaft c by the gears 1l 2, and thus an intermittent rotary motion is imparted to the feed-rollers g g.

The feed-rollers g g', the star-wheel h, and the guide-plate for the lap are all supported by connections from the shaftj on which the stud-wheel is mounted, and this shaft j also supports thereciprocating nippers 7c lo', which grip the lap as it is fed forward by the intermittent motion of the lap-rollers e e and feed-V rollers g g', so that when the shaft j is turned by the means hereinafter described the guideplate,r(not shown,) the star-wheel 71 the feedrollers g g', and the nippers 7c lo', with the end of the lap move from the position A they oc cupy in Figs. l and 2 to the position A', (see Fig. 4,) where the free end of the fiber held in the nippers 7o le is combed by the action of the revolving cylinder b.

When the fiber has been combed, the shaft j is again moved and the fiber, still held in the nippers 7o lo', returns with the feed-rollers g g and other parts to the original position A. The shaft j is actuated to impart the abovedescribed reciprocating motion to the nippers la 7c from the hollow cam Z, which is xed on the revolving shaft c and actuates by means IOO of a stud m the rocking lever m, which is pivoted on a short shaft 'm2 and connected by a link m3 to a lever m4, fixed upon the shaft j, which thus oscillates backward or forward as the stud m is moved-in lthe path of the hollow cam 7. y

The nipper 71; is fixed upon the arm 7a3, which is secured to the shaftj, but the arm 7c4 of the nipper 7c is mounted loosely on the shaft j and is kept normally closed against the nipper 71; by the side springs a, (see Figs. 2, 4, 5, and 6,) and in addition to the reciprocating motion already described for the nippers the nipper 7a has an independent reciprocating motion to and from the nipper 7c in order to seize and release the fiber as required, and this is effected by the following mechanism: On the shafto is fixed a lever o', on a stud at the end of which is mounted a bowl 02, which is moved along the path of a hollow cam p, fixed on the revolving` shaft d, and thus a rocking motion is imparted to the lever o and shaft o and to the lever q, which is also fixed on the said shaft. The lever q is pivoted to a link r, pivoted at r to a hollow cam f, mounted loosely on the shaft s', and this link r carries or has upon it a hooked finger r2, which moves forward with the link r and the cam t when the shaft 0 and lever q are rocked in the direction indicated by the arrow l on thelink r, and thus forces down a bowl 7a2, mounted on the nipper 7c', thereby opening the nippers 7c 7c', which then receive a fresh feed of lap fed forward by the rollers g g. When the nippers 7c 7c move downward to the position they occupy in Fig. 4, the stud 7a2 passes away from lthe finger r2 and allows the springs n to close the nippers 7c 7; on the fiber. Extra pressure is put on the nippers 7c 7a while the fiber is being combed by the cylinder b by means of the springs n, which act upon a shaft n2 by means of arms n4 and cause the stop-pieces n, secured to said shaft, to bear on the back of the nipper 7a', and thus assist in keeping it closed, as shown in Fig. 4. The springs n are compressed between adjustable plates a5 on rods n, pivoted to the frame at n?. From the nippers the fibers are delivered to the delivery-rolls u. The mechanism is so arranged and timed that the reciprocating nippers 7s 7c are opened as soon as they return to the position A with the tuft of fibers which has been combed at one end by the cylinder li', and simultaneously as the reciprocating nippers 7c 7c are opened the partially-combed tuft of fibers is seized by a pairof revolving nippers s, four pairs of which are keyed on the shaft s', which is driven one-fourth round at a time by spaced gearing (not shown) in the well-known manner, so as to impart an intermittent revolving motion to the nippers s, which are opened and closed by the reciprocating or oscillating motion of the cam t, which moves forward and backward with the link rand hooked finger r2, as alread y described. The partially-combed tuft of fibers lis thus seized by the revolving nippers s at the moment when the reciprocating nippers 7c 7c are opened and as the shaft s' is being turned through a quarter of a revolution, and the effect of this is that as the revolving nippers s move the tuft of fibersjs torn off from the lap held between the feedrollers g g", and this tuft is carried by the nippers s to the position B, as shown in Fig.

2, where the other end is combed by the cylinder b and the tuft is afterward carried forward by the nippers s. From the nippers the fibers are delivered to the delivery-rolls u. NVhen the reciprocating nippers 7r 7s are opened, the lap-rollers e e and the feed-rollers g g are rotated, as already described, and fresh fiber is fed forward to the reciprocating nippers 7a 7c.

Having now particularly described and ascertained the nature `of my said invention and in what manner the same is to be performed, I declare that what l claim, and desire to secure by Letters Patent of the United States, is
